Did you know?
Talus cave communities are not like typical caves. They occur amidst boulders or cobbles where openings form between rocks. They originate from layers of rocks and boulders that slip down a mountain or cliff. Animals that use talus caves for denning and cover include rattlesnakes, bobcats, porcupines, bats, and other small mammals and reptiles.
|State Ranking Justification||
There are a few hundred occurrences statewide. A few documented occurrences have good viability and few are protected on public land or private conservation land. This community is limited to areas of the state with fractured talus that accumulates at the base of cliffs and mountains. There are a few large, high quality examples in New York. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats that include mineral extraction and recreational overuse.
The number and acreage of talus cave communities in New York have probably declined slightly in recent decades as a result of mineral extraction and other development.
The number and acreage of talus cave communities in New York have probably declined moderately from historical numbers as a result of mineral extraction and other development.
